pesky popups

I get a pop up from a singles agency showing head and sholder shots of 'singles' available in my area (I am married and 81 so what the ?) running at the same time as I am going into my emails. I have looked for a delete sign or a tab I can close, but nothing. This only comes on when I look at my list of emails.

Just managed to get back on this PC to run Malwarebytes,
Carried out Step 1 'Getting Started' I now have the logs in Notepad.
Having problems with Step 2. Tried to download Main Mirror, to get GMER, too many options came up, found Rootkit/Malware but seemed to have tied myself in nots.
Where have I gone wrong? and what do I do now please?.
I don't seem to have the pop-ups now.

Correction to last message re Popups, I STILL GET THE POPUPS, they are small pictures of men or women scanning accross a small window to the right of my email window, suggesting I may like to choose a 'Single' from the men or women in my area. The answer is NO but as mentioned in my introduction to this thread, There is no way I can cancel the popups, I thought the Malware scan would have done that.
